I have my Ice link hooked to my CDC port in the trunk. When I press the CDC button on the head unit nothing happens. I was told to check the radio ground, so my question is, where is the grownd wire? Thanks in advance for the help.

The ground wire connects the chassis of the radio to the metalwork of your car and should be part of the loom.
